He also is a certified College-Level Instructor in the state of Florida and has done graduate work in Computer Science at the University of Florida. As the Technical Publications and Training Manager Simulation and Control Systems Department. General Electric Company Daytona Beach Fla. he currently is responsible for the costing. planning performance scheduling and timely completion of the Department's Technical Manuals and Technical Training Programs. These Training and Manual contracts cover Ship Systems Programs. Simulation Programs. and Communications Programs for the Armed Services and commercial customers. Mr. Hall has over twenty-years experience as a Technical Writer and Instructor and for the past seventeen years has been at the General Electric Company's Daytona Beach Facility. His experience ranges from teaching Basic Electronics and Radar Circuitry as a civilian instructor for the U.S. Army to writing Manuals Proposals Reports Specifications and Brochures for General Electric's product lines. Mr. Donald G. MOSS is a graduate of Kansas State University from which he received both his B.S. degree in Business Administration and his M.S. degree in Electrical Engineering. He is presently a Senior Systems Engineer for Control Systems in the Simulation and Control Systems Department at the General Electric Company's Daytona Beach Facility. He has been employed by General Electric for 23 years — the first seven as an Engineer and Program Manager on the Fire Control Systems for the Fleet Ballistics Missile Program the next six managing the design of control and checkout equipment on the APOLLO Program and the last ten years working on control equipment for the machinery plants of new Navy ships. Over the span of years at General Electric he has worked on propulsion control for the DD-963 propulsion electric plant and auxiliary control for the FFG-7: propulsion boiler burner electric auxiliary and car

Dynamic Simulation is defined as the hardware and software required to present to the student operator visual and audible cues and responses that are the same as those encountered when operating the Control Consoles aborad ship. This type of simulation is considered essential to the development of operator skills for critical tasks. Less critical tasks can be practiced using static simulation devices. This paper discusses the utilization of these types of training devices to train Navy crews. An overview of the Machinery Control Systems of the FFG 7 and AO 177 Class ships is discussed to provide an understanding of state‐of‐the‐art equipment development. The training programs for these two ship Classes are then reviewed to show how simulation devices are currently used by the Training Community, and this is followed by a brief discussion of the additional benefits that also are derived. © 1980 by the American Society of Naval Engineers, Inc.

Space-time tradeoffs for linear recursion 79

Space-time tradeoffs for linear recursion

A linear recursive procedure is one in which a procedural call can activate at most one other procedural call. When linear recursion cannot be replaced by iteration, it is usually implemented with a stack of size proportional to the depth of recursion. In this paper we analyze implementations of linear recursion which permit large reductions in storage space at the expense of a small increase in computation time. For example, if the depth of recursion is n, storage space can be reduced to √n at the cost of a constant factor increase in running time. The problem is treated by abstracting linear recursion into the pebbling of a simple graph and for this abstraction we exhibit the optimal space-time tradeoffs. © 1979 ACM.

The Effects of Microwave Radiation, Hyperthermia, and L-Ascorbic Acid on Ehrlich Ascites Carcinoma Cell Metabolism

引用

IEEE Transactions on Microwave Theory and Techniques 1978年第8期26卷 535-540页

作者： Piontek, Gerald E. Cain, Charles A. Radiation Oncology Training Program post-doctoral fellow University of Illinois Urbana II United States Bioacoustics Research Laboratory Department of Electrical Engineering Bioengineering Faculty University of Illinois Urbana II United States Department of Food Science School of Basic Medical Sciences Universitv of Illinois Urbana II United States

The effects of microwave radiation, hyperthermia, and L-ascorbic acid on metabolism of (U_14C) glucose, (2-14°C) glucose, and (1,5-l4C) citrate in Ehrlich ascites tumor cells (EATC) were studied. Microwave irradiated and water bath incubated cells were maintained at the same temperature for comparison. Data were obtained at 37.5°C and 42.5°C in the presence or absence of L-ascorbic acld, Ascorbilc acid increased the rate of metabolism of both glucose and citrate. No significant differences in glucose and citrate metabolism were found between irradiated and nonirradiated cells at the same temperature and ascorbic acid concentration. A comparison of glucose metabolism in a normal tissue preparation and EATC was made. Vitamin C did not increase metabolism in the normal cell preparation.

A Graph Model for Fault-Tolerant Computing Systems

引用

IEEE Transactions on computers 1976年第9期C-25卷 875-884页

作者： Hayes, John P. Department of Electrical Engineering Computer Science Program University of Southern California Los Angeles CA 90007 United States

An approach to fault-tolerant design is described in which a computing system S and an algorithm A to be executed by S are both defined by graphs whose nodes represent computing facilities. A is executable by S if A is isomorphic to a subgraph of S. A k-fault is the removal of k nodes (facilities) from S. S is a k-faulttolerant (k-FT) realization of A if A can be executed by S with any k-fault present in S. The problem of designing optimal k-FT systems is considered where A is equated to a 0-FT system. Techniques are described for designing optimal k-FT realizations of single-loop systems;these techniques are related to results in Hamiltonian graph theory. The design of optimal k-FT realizations of certain types of tree systems is also examined. The advantages and disadvantages of the graph model are discussed.

On the Properties of Irredundant Logic Networks

引用

IEEE Transactions on computers 1976年第9期C-25卷 884-892页

作者： Hayes, John P. Department of Electrical Engineering Computer Science Program University of Southern California Los Angeles CA 90007 United States

The constraints imposed by various types of irredundancy on the structure of combinational logic networks are investigated. It is shown that the usual notion ofirredundancy here called a-irredundancy, places bounds on the maximum number of inputs to certain types of network structures. A network is called b-redundant if it contains a cascade of single-input gates that can be reduced to either an inverter or a single line. Let Nab(Z) denote all realizations of Z that are both a - and b-irredundant. If N E Nab(Z), then the number of gates in any fan-out-free subnetwork of N is bounded. It is shown that a solution to some important design optimization problems can be found in Nab(Z). It is conjectured that Nab(Z) is finite and some results supporting this conjecture are presented. For example, it is impossible to construct an arbitrarily long cascade of networks that perform the identity transformation without introducing a-or b-redundancy. A more general type of redundancy, c-redundancy, is defined which includes both a-and b-redundancy as special cases. The class of c-irredundant realizations of Z is finite.

The usefulness of software monitors in testing large ‘programs is discussed. Several types of testing strategies based on the use of monitors are surveyed. Since there is a computational overhead involved in employing monitors, attempts are made to minimize the number of monitors employed. This optimization problem is formulated and analyzed in graph-theoretic terms. Implementation aspects are considered through both discussion and examples.

Journal of the ACM (JACM) 1975年第4期22卷 551-571页

作者： Hayes, John P. Department of Electrical Engineering and Computer Science Program University of Southern California Los Angeles CA 90007 United States

The problem of determining the amount of fanout required to reahze a switching function m investigated. The significance of fanout in switching networks is discussed Fanout-free functions are introduced and their propertms examined. Two relations, adjacency and masking, are defined on the variables X of a functlon f(X), and these relations are used to characterize fanoutfree functions A quantity τ(f) called the input fanout index of f is defined for arbitrary switching functions;τ(f) represents the minimum number of input variables that require fanout in any reahzation of ff It is shown that τ(f) can be determined from the pmme lmphcants and prime imphcates of f using two additmnal relations on X, the conjugate property and compatibility An algorithm is presented for finding a reahzatlon of f in whmh only τ(f) variables fan out. Some other measures of fanout are briefly considered. © 1975, ACM. All rights reserved.

On Modifying Logic Networks to Improve Their Diagnosability

引用

IEEE Transactions on computers 1974年第1期C-23卷 56-62页

作者： Hayes, John P. Department of Electrical Engineering and Computer Science Program University of Southern California Los Angeles Calif. 90007 United States

This paper considers the use of control logic to reduce the number of tests required by a logic network and to simplify test generation. The properties of EXCLUSIVE-OR (EOR) circuits as control elements are examined. Systematic procedures are presented for modifying any combinational or sequential network so that the resulting network requires only five tests. These tests can easily be generated using a set of predefined test patterns of length five. The design of diagnosable networks using a limited amount of control logic is also discussed. © 1974, IEEE.
